Acknowledgments

I take this opportunity to thank Dale L. Hoyt, Thomas E. Moore, and
John Wellman, who ably assisted in collecting and studying these frogs
in the field. I am indebted to Floyd L. Downs for permission to include
specimens collected by him and John Winklemann. My studies on hylid
frogs are supported by the National Science Foundation (Grant G 9827).
